tfenv can't find installed versions

[jtokoph]

Update

If anyone has the same problem and finds this, it's because the latest version of tfenv installable via homebrew is out of date and doesn't include this MacOS fix: #152

The solution for me was to follow the manual install procedure in the readme: https://github.com/tfutils/tfenv#manual

Original Issue
I'm installing versions of terraform with tfenv but it can't seem to find them after installing:

➜  tfenv --version
tfenv 2.0.0

➜  tfenv install 0.12.29
Terraform v0.12.29 is already installed

➜  tfenv use 0.12.29
No installed versions of terraform matched '0.12.29'

➜  TFENV_DEBUG=1 tfenv use 0.12.29
